Voluntary cancellations are probably an improvement!
Yeah, being dictated to by another country's dictator about what is and isn't permissible freedom of expression [guaranteed by our own constitution in fact] is a pretty big improvement over the status quo
Much better world to live in now that Sony has capitulated their right to expression in exchange for... not getting attacked by an imaginary group. The precedent has been set, you don't even need to be a credible and real terror group to shut down hollywood. God help us if, I don't know, ISIS threatens to bomb the next movie showing. Why not shut that down, it's a real terror group threatening it. If a made up threat by a blowhard government with no ability to conduct anything can shut down a movie like this, then I guess we may as well hand over the entire publishing department to terrorists so they can vet our choices of media before we have to deal with these cancellations.
Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
Better safe than sorry, right?
